Merge branch 'master' into esp8266

* master: (414 commits)
  Don't export sketch if the underlying core does not support it. Fixes #3171
  RSyntaxTextArea: using a modified version, tracked at https://github.com/arduino/RSyntaxTextArea. Fixes #3099
  Updated keywords.txt
  New editor on MacOSX: since CMD+J is known as "jump to selection" and the editor has no such feature, CMD+J is disabled on mac. See #3098
  Old Preferences class remains for backwards compatibility as a delegate for PreferencesData
  New Preferences window: renders fine on every OS and it's easier to adapt using NetBeans as visual editor. Fixes #3140
  Remove spawn from exec command
  Removed redundant call to File.deleteIfExists()
  Removed buggy redundant check in FileUtils.deleteIfExists()
  Restored current line/current selected lines display on lower left of the IDE. Fixes #3134
  Updated cursor.ino
  New editor on MacOSX: restored CMD+E for finding selected text
  New editor on MacOSX: CMD+UP/DOWN moves cursor to start or end of sketch. See #3098
  New editor on MacOSX: CMD+BACKSPACE deletes current line until cursor position, ALT+BACKSPACE deletes previous word. See #3098
  ArduinoIDE is in the default package. Removed
  Fixes  #2969:
  Fix Uncategorized warning message
  New editor: ALT+ BACKSPACE deletes next word (OSX only). See #3098
  New editor: ALT+ UP/DOWN move current line only if "editor.advanced" (hidden pref) is true. Fixes #3101
  New editor: mark occurrences enable when "editor.advanced" (hidden pref) is true. Fixes #3102
